Onions, also known as “bulbs” or “roots” in some parts of the world, grow from a single root system. Each plant has many small bulbils (or bulbs) connected with strings called flower stalks.

The edible part is a small, white bulb that grows underground. The bulb is surrounded by thin layers of skin that can be either brown or green. Onion skin is also edible, but most people remove it before cooking. When the onion is chopped, the individual bulbils break open and release a flavorful juice.

Onions have been cultivated for thousands of years. They are believed to have originated in the Middle East and Asia, but evidence shows that onions were grown throughout Europe during ancient times. The Egyptians considered them sacred, and many believe they were used as currency. There are records of onions being traded for gold!

How do onions grow?

Each layer of leaf grows from the center of the onion plant, which was planted as a tiny seedling in early spring. The leaves grow through summer until fall, when days begin to get shorter and cooler weather sets in. Onions do not like cold weather, so they start to bulb up and form the edible part of the onion.

The leaves at the top of the bulb die off and turn brown, but new leaves will continue to grow from the center of the bulb. So if you leave an onion in your garden over winter, it will keep growing fresh leaves until the weather gets too cold and it dies.

Onions can be grown from seeds or small onion plants (also known as sets). However, seeds take longer to grow into mature bulbs, so most gardeners prefer to plant sets.
